POP Collision Detect

Keyboard Shortcuts

In this video, Scott Pagano explains how to use the POP Collision Detect node to have particles build up on your ground geometry. Learn techniques for creating interactions beteen particles and collision geometry in Houdini.

- [Instructor] Now we're gonna add in…the ground collision for these particles,…because that's a big part of a simulation…like this because we have this emission…happening, but we want to have…those actually impact the ground.…Let me go up a level back to our objects…and we're gonna take a look inside…our ground geometry object here.…I've created just a piece of simple…ground geometry using the new height…field stuff in Houdini 16, and I've cashed out…just a polygonal piece of geometry for you.…You can see down here, kind of like we…had in our object network, there's…a bunch of different things going on…because I basically have a bunch of different…versions of this geometry for different purposes.…

Under our out node here, this is just…our render-able geometry, this is just…a simple plane of noise basically.…There's our ground, but then I've…also just threw a few other sop nodes,…created this out for particle collision,…where we have created an object with some…thickness that we need for particle collision.…Then you can see over here I have…

Explore the massively powerful particle system in Houdini. In this course, join Scott Pagano as he walks through how to use particle systems in Houdini. Scott takes you through four different projects that help you understand how to use particles with sprites and geometry instancing, and how to create trails and impacts. He shares how to create some emission off of a moving object and then create a smoky particle effect, how to create geometric trails streaming off an object, and more.
